Shaping the surface of optical glasses with picosecond laser and adaptive optics

Abstract

An application of a liquid-crystal-based spatial light modulator (LC-SLM) for shaping the surface of Borofloat®33 glass is presented. In this approach, high-repetition-rate picosecond laser pulses of wavelength 515 nm are patterned with an SLM, and delivered to the workpiece in order to generate specific surface deformations. Since optical glasses such as Borofloat®33 are transparent to visible light, the glass surface is coated with a thin layer of graphite prior laser treatment in order to increase absorption of the workpiece, so that localized melting of the glass surface is obtained. In this paper, we also investigate the interaction of the graphite-coated glass with nanosecond laser pulses, showing that it is possible to produce simple diffractive optical elements, e.g., sinusoidal gratings with a 25 μm spatial period, using 65 ns laser pulses at a 1064 nm wavelength.
